I'm setting up my first rack from c serpent today and i'm just wondering what you guys have your racks set too??? i know that everyones setup will be different depending on the temp of the room and all that but just trying to figure out what ball park i should be in right now it's set to 90 degrees but still warming up

My BP rack is set to 90.4 because I'm using substrate, otherwise I might set it at 88 or so

What are u guys using to measure temps heat guns or thermometers and where do u take the temps at
